INSECT-EXTERMINATING APPARATos;

Ap'plication filed ApriilS, 1924. Serial No. 707,686.

To all whom it may concern:

Be it known that 1, ROBERT E. HAMMOCK, a citizen of the United States,res ding in Dunklin County, State "of Missouri, have, V invented certainnew and useful Improvements in InsectEXterminating Apparatus,

of which the following is a-specification,

reference being had to the accompanying drawings. r

This inventionrelates to certain improve-- ments in insectexterminatingapparat-u'sand it ispriinai'ily an object of the invention to providenovel and improved means whereby the destruction of the insect isefiected by cremation.

The invention also has for an object to provide a novel-andimproved"apparatus of this character especially designed and adapted ford'est-ipying boll" weevils and other insects that infest cotton andwherein the insects dislodged from the plants are collected in a pan orpans serving as an in- It is also an object of'the invention to providea novel andimproved apparatus oft-his general character comprising aportable structure and pans operatively engaged with such structure fortravel between plant rows together with means for dislodging the in- Isects from the plants and for destroying v such insects collected withinthe pans.

An additional object of the invention is to provide a novel and improvedapparatus.

of this general character embodying pneumatic means fordislodgingtheinsects from the plants together with an agitating memhercarried by the structure for direct contactwith the upper portionsof.the, plants to effect afurther a'gitationthereof to dis lodge theinsects thereon.

Another .ob 'ect ofthe'inventi-onis to pro vide a novel and improveddevce of this general character comprising; a portable structure togetherwith pa-ns-operat ively en.-

gaged therewith and positioned to travel -between adjacent plant rowstogether with means. for. raising said pans to an 2inofperative positionwhen the apparatus is noti'n' use or to facilitate a turn at the end ofa plant row. 'f The invention consists in the details of constructionand in the combination and arangein ient of the several parts of my-aim-1 "insect v ienterininating apparatus proved j I 7 again ;advantages'are the 'supporting'wheels W.

attained and the device rendered simpler, less BXPBHSIVG and otherwisemore convenien-t'and advantageous for use, as ill be hereinafter morefully set forth. a

The novel'features of my invention will hereinafter be definitelyclaimed. 1

In' order that my invention may be the better understood, I will'nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a view in top' plan illustrating anapparatus constructed in accordance with an embodiment of my invention;

Figure 2 is a view in rear elevation of the elevation and partly insection of the means for raising and lowering the pans;

Figure 6 is a vertical sectional view taken substantially through thelongitudinal center of the machine as illustrated in Figure 1;

Figure 7 is an enlarged transverse sectional View taken through, one ofthe pans I A as herein employed;

Figure 8 is a fragmentary view in" perspectiveofa side apron forcoact-ion with a pan;

- Figure 9 a fragmentarylongitudinal sectional view taken through a panas herein disclosed;

Figure '10 is a view intop plan of a burner; and Figure 11 is anenlargedfragmentary view partly in elevation and partly in section of one of thespraying members or'noz zles. As disclosed in the accompanying draw-'i-ngs', A denotes-an arched axle of desired dimensionsijbut preferablyof a'length to" straddle, three plant rows, the opposite ends of theaxle being provided with the 'outstanding spindles 1 upon whicharefinounted The vertical side .inembers 2 at -a predes terminedpoint-above the spindles l are provided with the forwardly direct-edarms 3 1 connected at their outer ends by the cross member 4 andintermediate their ends by the spaced cross members 5 and 6; Restingupon theicen'tral portions of {the members t,

tongue T, said tongue being bolted, as at 7, to the forward member 4.

Resting upon the rear portion of the tongue T is a tank l3 held inapplied position by the straps 8 disposed over the tank 13 and under themembers and 6 at opposite sidcs of the tongue.

'Eiupported by one of the arms 3 is a fan or air compressor F,preferably of a rotary type and which is in communication with the tankB through the pipe 9. The fan or compressor F, as herein disclosed, isoperatively engaged with one of the wheels W by the chain 10 so thatwhen the apparatus is in transit, air under pressure may bestored withinthe tank B and said supply being substantially maintained during theperiod the air is being exhausted from said tank.

A seat S is positioned substantially above the axle A and is carried bythe spring 11 suitably anchored to the tongue T.

In communication with the tank B is a rcarwardly disposed pipe 12tern'iinating in a depending portion 12 and with which depending portionis telescopically engaged a vertically disposed pipe lat. said pipe l-iand pC-llJlOll 12 being maintained against relative movement in awell-known manner by the holding bolt 15. The lower end portion of thepipe 14 is in communication with a n'ianifold pipe 16 extendingtransversely of the apparatus with its opposite ends closed, said closedends being continued by the offset extensions 17 adapted to beadjustably connected, as at 18, with the side members 2 of the axle A.The manifold pipe 16 is adapted to be raised or lowered in accordancewith the heighth of the plant rows being treated and the adjustableconnection of the extensions 17 with the side members 2 of the axle Apermits said manifold pipe to be effectively maintained in desiredadjusted position. The manifold pipe 16 is further maintained in its rquired working position by the holding bolt 15.

The apparatus, as herein disclosed, is of a type particularly designedfor simultaneous treatment of three plant rows and de pending from themanifold pipe 15 are the spraying members or nozzles 19 adapted to bepositioned substantially directly above the plant rows so that theairdischarged thcrethrough from the tank B will strike the plants fromabove, the air blast serving to dislodge boll weevils or other insectsfrom the plants,

The pipe 12 has interposed therein valve of any desired type whereby thedis charge of air from the tank B may be read ily regulated orcontrolled.

The side members 2 of the axle A. at the upper ends are provided withrelatively their outer ends connected by the transversely disposedmember 22.- interposed be 1,sso,eo

tween each of the arms 21 and the adjacent member 2 is a diagonallydisposed bracing bracket or member 23. Pivotally engaged with each ofthe brackets or members 23 and disposed therethrough is a spindle 24provided at its inner end with a depending .arm 25 adapted to beadjustably connected with the upper end portions of the elongated arms26. The lower portions of the arms 26 are tied or connected by thespaced parallel members 27 and to said members 27 and the portions ofthe arms 26 between said members are secured, as at 28, the marginalportions of the flexible strip 29 pre ferably canvas. As the apparatuspasses over the plant rows this flexible member or canvas 27 togetherwith the parts associated therewith constitutes an agitating meansadapted to have direct contact with the up per portions of the plants toprovide additional means for effectively agitating such plants and.dislodging therefrom the insects thereon. The adjustable conectionbetwcc. the arms 25 and 26 permits the agitating member to be positionedor arranged as the occasions of practice may best require.

In practi e, the wheels ii are adapted to each travel between adjacentplant rows with, as hereinbefore stated, three rows between said wheelslV. Travelling between adjacent rows arranged between the wheels are thepans P and between the outer of said 10\ s and the wheels W are the pansP.

The pans? and P ravel on the ground and are of suliicient weight tocrush the bolls 01' squares or other insects which may drop to upontheground ahead of the pans. Each of the pans P is of desired length andof a width to substantially bridge the space between adjacent plantrows. The forward end portions of each of the pans P is rounded frombelow, as indicated at- 80, and the opposite or rear end constitutes adoor 31 to permit access within the pan and particularly when desired to'einove a burner or to clean out the pan.

Arranged within the pan are the transversely spaced and longitudinallydisposed siv with the length of the pan l and bridging the space betweenthe side walls thereof as is particularly illustrated in Figures 6 and 7of the accompanying drawings. Each of the burners C comprises a cup likememher having its upper end open and which is in communication with asupply pipe through the medium of the depending nipple said nipplecoact-ing with the pipe to short forwardly directed arms 21 having"support the burner in applied position.

The pipe 85 extends along the lower port on of. h ompar m nt 3.3 and iscommon to the spreader directly above the burner-being web-shaped incrosssection. I a

The bottom portion of each of the burners C is n'ovided with a packing40 of asbestos paper. Fitting within the upper portion of the burner andresting upon said packing or paper 40 is a plurality offiues.41,"adj,acent tlues being preferably connected one to the other.The packing or paper is saturated by the fuel, whichispreferablykerosens and when the burner is ignited the flames are emittedfrom; the lines "41,. and through the i-nstrumentality of the associatedspreader 39 theflames are caused to contact with the floor 34 over arelatively large area whereby suliicient to eiiectthe desired cremationof the weevils or the like received thereon.
